In 1965 when this movie was made, the 'Spy Genre' was definitely in: Power-hungry schemers trying to rule the world, fast cars, beautiful babes, exotic locations, and fancy gadgets. This movie is no exception, and has everything. The story goes from Italy to Spain to London as it follows two buffoons who accidentally stumble on a plot to take over the world. Our two heroes are in terrible danger and stumble wherever they go, and along the way they are noticed by the British Secret Service. The Service decides to hire them and put them to work as real spies! The references to 'Goldfinger' are frequent and obvious, but not overdone (at least to this viewer). Yes, it is a silly movie but still enjoyable.
The two buffoons in this movie were actually famous in Italy in the 1960s for making many such comedies. They played spies and policemen, and were constantly getting into grave trouble. They were both very silly, so parallels with 'Laurel and Hardy' or 'Martin and Lewis' were not accurate; neither of them played the role of 'straight man'.
